or leveling dirt or filing piled up alongside.

the track, in the form of ridges or mounds;

and the invention morepartlcularlyrelates to certain features ofConstruction pertaining to the method of mounting and operating thewings of .the'spreader, whereby the latter may beadjusted and raisedandlowered to meet the requirements of use.

The invention further relates to the formation and method of mountingand operating the supporting arms for the spreader wings, Where y thevertical elevation and lateral distention of the win' s can be adjustedat a. single operation, and y means of pneumatic or other power, thusfacilitating the o eration of the device and enlarging its fie d ofoperation.

The invention further relates to the mounting for permitting verticaladjustment of the s reader wings, and to the arrangement 0 sheaves androllers, whereby the friction is mimimized, and the adjustment of thewings facilitated. j

The invention further relates to the construction and arrangement of thewing braces and to the mode of adjusting the same; also to the arranement of pressure cylinders and pistons -or operating the mechanism;

j also to the constructionand arrangei'nent of the entire car body, andthe mode of reinforcing the same and securing the various operatingstructures'thereto.

. The invention finally consists in the features of construction andcombinationof parts hereinafter descrlbed and claimed.

In the drawings Figure 1 is a side elevation of the entire spreader,showing the spreaderwing lowered and distended; Fig. 2 a to or planview'showing', one of the wings disten ed, and the other wing retractedor folded back; Fig. 3 a rear end elevation, showing one of Fig. a crosssectional detail of the car bod showin the arrangement of sheaves on t eforwar bridge; Fig. 5 an inner face view of This invention relates tospreaders for use the mounting for one of the wings; Fig. 6 a crosssectional elevation taken on line 6-6 of Fig. 5, looking in thedirection of the arrow; Fig. 7 a top view of the mounting; Fig. 8 adetail, showing the mechanism for raising and lowering one of thesupportiiw arms Fig. 9a side elevation of the same, s owing the armprojected Fig. 10 a sectional view of the same and Fig. 11 a detail ofthe-wing hanger.

Referring to Fig. 1, the mechanism 1s carried by a flat car bed 11mounted upon forward trucks 12, an rear trucks 13 of the usualcharacter. The car body is preferably I of somewhat less width than thestandard, in

order to accommodate the wings when folded alongside the car and ermitthe car to travel under standard con itions. The car has -mountedthereon a forward bridge 14 and a rear bridge 15, which serves to suport various structures and mechanisms to e hereinafter described. Theforward bridge comprises a cross beam lfi, which is supported by meansof two pair of divergent uprights 17, which serve to elevate the beam 16a considerable distance above the car level. The rear bridge likewisecomprises across bear-Ii 18, which is supported by means of two-pair ofdivergent uprights l9. vThe forward] bridge, furthermore, is providedwith dia'gonal braces 20, as shown in Fig. 4; Forward of theforwardbridge, on each side of the car, and outside of the edge thereof,is a guide post 21, the lower-end of which is supported within astep 22,shown in dotted lines in Fi 1 which uide osts, above the floor'lcve,,

l g P are space and s'u ported by means of a cross brace23, the en s 24of which are clamped around the vertical guideposts and serve, inconjunction with the steps, 'to hold the guide posts rigidly in positionand out of contact with the sides of the car. The cross br'ace23 issupported, near its ends, upon raised side frames 25, elevated above thecar level.

26, whi wings consist of a timber backing 27 and aplate metal facing 28.The inner forward ends of the Wings are entered between inner and outerattaching plates 29 and 30 res ectively, which lates project rearwardlyrom and are rigidl y securedto a pivotal mounting head 31, 'as shown in,Fig. 5, which head '18 of enerally rectangular formation having itsfower forward corner Each plost serves as a guideway for a wing cut awayand above the cut away corner, on

' 33, within which are mounted four sheavesb? means of the central1pivot bolt 35 and a p u t 3.4, adapted to bear against the opositesides of the vertical guidepost, Whic 1s rounded to permit aswingin movement of the wing as well as an-up an down movement. [Theinner and outer sideplates are securedtothe interposed mounting ,head31,-by means of bolts, or in any other suitable manner; and the wing issecured between the side plates rality of clamping he s 36 arranged in aring, which arrangement permits the Wing to be raised and lowered uponthe pivotbolt35 as a center, and held in adjusted position by theclamping bolts. in addition to the lower bearing sneaves'34 is a guidebearingsheave 37, which is pivoted nut-hm, a mounting 3S embracing theguide post a considerable distance above the wing, which mounting is secured to the head byinea'ns of a vertical bar 39, which is supplementedby a diagonally extending brace bar 40 which is hooked onto the wing atits outer endand is adjusted by means of a turn buckle 41. This methodof pivotaily mounting the wingpermits it to ride up and down the guidepost asa bearing, and permits it to swing aroundisnch ostto any positionof lateral adjustment, an "these movements will. be ea'eil performed by"rea son of the very c'hnsidera le distance between the upper and lowersheaves, whichobviates any cramping or wedging which. might take widelyse arated. i v

Eacho the wings is adapted to beraised and lowered and folded by meansof a supporting arm 42, which engaiestm wing at a point about one iourthof t e distance from the front to the rear thereof and'is oi thepeculiar shape best shown in Fig. 3. Thesupporting arm, in its entirety,comprises a straight inner ivotal end 43, a supporting portion M, an anupturned attac 1n en the, pivotal end portion by a shoulder 46, and

when the arm is in depressed position, as best shown in Fig. 3, the mainor supporting ortion of the arm will bmslightly incline towards itsouter end, and will extend in sub stantially transverse relation withres ect to the rearwardly divergent wing with w. ioh it cooperates. Thewing is connected with the supporting arm by means of a hanger 47,

best shown in Fig. 11, which comprises a yoke 48, between the arms ofwhich is ivplace if the bearing points were not thus prises amainsection behind the rear trucks.

The supporting portion is connecte with,

' scares mg arm'is loosely mounted between cars 51,

which outwardly, roject from a slidable block 52 mounted whicharerigidly secured to the end of the forward bridge; The-block isprovided, on its rear face, with teeth 54, which cooperate with a dog 55ivotally rnounted between cars 56 rearwardl y extendin from the guideway53. The dog is provi ed with a rear" wardly extending lever arm 57,which is ada ted I to be retracted by suitable trip inec anisin 58,which is under the control of the operator. The slidable block 52 andthe parts connected therewith are adapted to e raised and lowered by,means of a motor cylinder 59, which is preferably connected with areservoir 60, which is adapted to be charged with compressed air fromthe train brake system through a pipe 61,01 is,adapted to be suppliedfrom any other source of comressed air, or other medium under pressure.

within guideways 53,

it is to be understood that the mechanism heretofore described is dolicated on both s des of the car, so that furt ier description of thesefeatures is deemed unnecessary.

'accommo atefthedivergent position of the wing, Thobraces are oftel'esco lc-formation, and, e'xc'eptfor diilerence-in on th, are

of uniform construction, s o that a cscrip tion;cf. .tlie rearor-longest braces 64will apply. to the othertwo' 'mhe brace 64comofK-beam formation,

whicli terminates, atits rear end, in a tongue 7 66, which is pivotedbetween crpss beams 67 which are p'ositioncdlbelow the car body andBetween the flanges of the I-beamfifi aremo'unted a pair of oppositelydisposed channelbeams 68, which con-.

stitute t e outer section of the telescopic brace- The-channelxbearnsare adapted to. be adjusted with respect. to the I-beam, with which they'coo erate, ander'c. held in adjusted position y means of bolts 69,which arrangement permits the lengthjof the braces to be variedconsiderably by removing tlie bolts and adjusting the channel beamsections with respect to the I-bcam until the desired length of brace issecured; The on ter ends oFthe channel beams are connected, as shown' inFig. 2, by means of a tie plate 70 provided with a depending pin 71, andthe ends, thus connected, are supported, when in lowered position,within an outer seat 72 on the inner side of the wing, which sent isprovided. with a hole 73 adapted to receive the pin or stud 71 when thebrace is lowered. It will be understood that the method of mountin andpositioning the forward and interm'e'late braces is the same as thatpertaining to the outer brace, so that further dcscription of theseparts is deemed unnccessary.

The intermediate and rear braces are connected by means of a cross brace74 of I-bearn formation, which cross brace is pivted, at its ends,between cars 75 on the intermediate and rear braces, which connection isa loose one and permits a slight amount of play or movement when theparts are being raised and lowered, which is essential ,to the properoperation of the arts. In like'mancylinders are located upon thelower cyto convey sheave 82 secured to the beam 16 of the orner the intermediatean forward'braces are connected by means of a square rod or shaft 76,which engages the forward brace near its inner or pivoted end, whicharrangement of braces and cross braces serves to firmly maintain thewing in its distended position and enable it to withstand the strainofactual usage. a

Near the rear end of the car are located a pair of lower pressurecylinders 77 adapted to operate the wing supporting arms, and a pair ofupper to raise and ower the braces. The upp ward bridge. The sheavesabove referred to serve to guide a cable 83, the'end of which isattached to the outer end of the supporting arm. The cable, thusattached, is passed over the upper guide sheave 8 2 and the'lower guidesheave 81, and thence around the actuating sheave 80, the end of thecable being piston 84, having, on its en then fastened to any suitablefixed portion of the car structure. This arrangement is one which givesa movement to the end of the supportin ,arm, twiceas reat as themovement of t e piston. In li e manner the uper cylinder 77, which ispreferably smaller tflh n the lower cylinder, is (provided with a asheave in elinement with a guide sheave 86 which is mounted upon a crossbeam 87 on the forward bridge, and the sheave 86 cooperates with a guidesheave 88, suitably secured to the rear bridge, which lower guide sheaveis immediately beneath and in alinement with an upper guide upon andsecured to the cross beam 18 of the rear bridge. The several sheaves,above referred to serve to guide and actuate a cable 190, the outer endof which is attached to a the cable being. thence passed up over thetop'guide sheave 89, thence passed around 'In order to more ressurecylinders 78, adapted sheave 89, which is positioned 91 rigidly securedto the cross brace 41,

the lower guide sheave 88, thence forward around the sheave 86, thencearound. the actuating sheave 85, and finally secured to a fixed portionof the car structure. This arrangement gives a movement to the outer endof the cable equal totwice, the movement of the piston. The pressureis-supplied to the respective upper and'lower cylinders by means ofpressure supply pipes 92, which are connected with the storage cylinderin any suitable manner.

The outer late 29 of each of the wings is 'providedwit aforwardlyprojecting guard 93 which, when the wing is extended, projectsin close proximity with the rail and is adapted to protect the railagainst the dir'tor' filling whic might otherwise accumulate. thoroughlyinsure the rail against obstructions a wedge shaped pilot 94 isemployed, which is pivotally mounted at5 the forward end' of the car bymeans of de pending brackets 95, and the pilot is ada ted to be raisedby means of the cable 96 w iich is carried over'a sheave 97 and extendsrearwardly and'connects with the lower actuating sheave 80, the cablebeing of proper length to ive the necessary movement to raise the pi otaway from the track to the desired elevation. securing or bracing theseveral structures previously referred to, a series of adjustable racerods 98 are employed, which brace and support the guideposts 21 and theforward and rear brid e structures, and the brace rods are 'pre erablyprovided with turn buckles, so that the entire structure can betightened up at will.

' In use, with the wing raised and inwardly folded, as shown at theright of Fig. 3, the supporting arm will be pulled up by the retractionof the lower piston rod and the tension of the cable, and when thesupporting arm is in this position, the hanger 47 will be supported bythe shoulder 46, which will be raised sufficiently, above the pivotalpoint, to cause the wing to clear the track surface. The wing will alsobe thrown back in substantially parallel relation with the car by reasopIn addition to means forof the fact that when the supporting arm-1sraised the shoulder portion thereof will be in substantial longitul inalalin'en'icnt with the vertical guide post which affords the pivotalmounting for the forward end of the wing.

With the parts in this position, a forward movement of the lower pistonrod and actuatmg sheave serves to release the supporting arm, which willdescend in substantially the osltion shown in Fig. 3.' Asthe arm is reeased the sheave in the hanger 47 will roll down from the shoulder andonto the main or supporting portionof the arm, and this movement lowersthe wing proportionately to its outward or swinging movement. 1 The.provision of the shoulder permits the wing to be supported upon thearm-a considerable distance above its pivotal point, and the shoulderformation provides a specs, when the arm is raised above the shoulder,for the reception of the wing which is thus enabled to lie closely upagainst the on! body at this point. As the ri-rm is lowered hangersheave will roll out along the arm until the limit of distention hasbeen reached, in which .osition the main or supporting portion 0 the armwill have e'slight incline toward its outer end, which incline permitsthe weight of the arm to serve as the means for swinging it intodistendedposition. As the arm is thus distended the universal swiveljoint of the -h anger will permit the wing to move into its in tendedposition without j emming or binding of the hanger sheeve which alwaysIneinteins its proper enga 'ement with the upper surface of the arm.'ihe pivotal mounting for the g arm, moreover, is one which permits 0.sufhcient horizontal play or movement to socommodate the arm to thedifferent engiesof distention of the Wing, and this movement of the arm,in conjunction with the movement 5 afforded by the universal swivel ointfor the anger, gives en easy and uninterrupted movement to the wingwhich is enabled to swing outinto position hy grsvity when the eim sreleased. The pivotal mounting for the win on the vertical. post, is onewhich gives it ee up and down movement, so that the win when the arm islowered will auto kinetics y adjust itself, both with respect to itsverticel elevation and with respect to its 5 angle of distention, andthat without binding or crampin which is prevented by the up or andlower s eave hearings for the wing. he wing can be furthermore adjusted,as to its ,vertical elevation, by the motor cyiinder 59, whichis'edapted to adjust the pivotal mount ling for the inner end of the armto any de {sired degree, and the dog 55, which engages with the teeth onthe slidable block, serves to "provide e'positive support for thepivotal regardless o the pressure in the ,motor c iinder. The formationof the braces 'is'jone w 'ch permits further adjustment with "respect tothe angle of distention ofthe wing, since the length of the braces canbe varied, ,asdesired, in order to accommodate the wing to differentangles of distention.

The device, as a whole, is one which permits the various adjustments tobe readily and quickly made by a single operatonend dispenses with allmanual work in operating: the spreader. T he peri s, when'not in use,can be adjusted in such small oonipsss that thewidth' of the entirespreader will not be great-er siibstantially, than ordinary ii at cars,so that the spreader can be run over any track without removal of any ofthe parts, which, of course, is edvsntagi-x in actual use. Theeinployrne oiconipressod air from the train pipesarises with thenecessity l'or, providing snnidependent eogine or motor for the.spreader and the some time permits sufficient pressure to be stored upin the reservoir so thet the device can he operated even thoughdisconnected fl who train 13,
